Hierdurch können die empfindlichen Hydraulikkupplungsteile, welche vorzugsweise eine gewisse federnde Lagerung aufweisen, problemlos gekuppelt werden. Anschließend oder gleichzeitig kann die mechanische Verriegelung zwischen dem Mastschlitten und der Werkzeugeinheit über eine Verriegelungseinrichtung erfolgen, welche von der Hydraulikkupplung beabstandet ist. Die mechanische Verriegelung kann unmittelbar am Rahmen der Werkzeugeinheit mit dem Mastschlitten erfolgen.A basic idea of the invention is to provide the tool unit with a tool guiding device so that the tool unit can be guided directly on the mast guide. After the tool unit is mounted and positioned on the mast guide, coupling of the mast carriage with the tool unit can be largely automatic. In a collapse or pushing together of mast carriage and tool unit by the mast carriage by the carriage drive, in particular a winch or a hydraulic cylinder, is moved, first, a connection between the two hydraulic coupling parts can be made. As a result, the sensitive hydraulic coupling parts, which preferably have a certain resilient mounting, can be coupled easily. Subsequently or simultaneously, the mechanical locking between the mast carriage and the tool unit can take place via a locking device, which is spaced from the hydraulic coupling. The mechanical locking can be done directly on the frame of the tool unit with the mast carriage.
Auf diese Weise ist eine weitgehend automatische Verbindung von Werkzeugeinheit und Mastschlitten ermöglicht. Dies erlaubt ein schnelles und effizientes Wechseln der Werkzeugeinheit ohne zeitaufwändigen Einsatz von Bedienpersonal. Durch eine einzige Bewegung des Mastschlittens oder der Werkzeugeinheit kann die hydraulische und die mechanische Verbindung der beiden Bauteile hergestellt werden.In this way, a largely automatic connection of tool unit and mast carriage is possible. This allows a quick and efficient change of the tool unit without the time-consuming use of operating personnel. By a single movement of the mast carriage or the tool unit, the hydraulic and the mechanical connection of the two components can be produced.
Eine bevorzugte Ausführungsform der Erfindung besteht darin, dass das erste Hydraulikkupplungsteil und das zweite Hydraulikkupplungsteil mehrere Kupplungsstecker beziehungsweise Kupplungsmuffen aufweisen. Grundsätzlich können an einem Hydraulikkupplungsteil nur Kupplungsstecker und an dem gegenüberliegenden Hydraulikkupplungsteil nur die korrespondierenden Kupplungsmuffen vorgesehen sein. Kupplungsstecker und Kupplungsmuffen sind dabei jeweils so ausgebildet, dass diese eine passende hydraulische Verbindung im zusammengeschobenen Zustand bilden. Neben Steckern und Muffen für hydraulische Verbindungen können auch Verbindungselemente für Elektro- und Datenleitungen im Bereich der Kupplung vorgesehen sein, welche entsprechend verbunden werden. Die Hydraulikquelle kann insbesondere ein Hydraulikaggregat sein, welches an einem Trägergerät oder separat davon angeordnet ist. Über entsprechende Leitungen ist die Hydraulikquelle mit dem ersten Hydraulikkupplungsteil am Mastschlitten leitungsverbunden.A preferred embodiment of the invention is that the first hydraulic coupling part and the second hydraulic coupling part have a plurality of coupling plugs or coupling sleeves. In principle, only one coupling plug can be provided on one hydraulic coupling part and only the corresponding coupling sleeves on the opposite hydraulic coupling part. Coupling plug and coupling sleeves are each designed so that they form a matching hydraulic connection in the collapsed state. In addition to plugs and sockets for hydraulic connections, it is also possible to connect electrical and data cables in the area of the coupling be provided, which are connected accordingly. The hydraulic source may in particular be a hydraulic unit which is arranged on a carrier device or separately therefrom. Via corresponding lines, the hydraulic source is line-connected to the first hydraulic coupling part on the mast carriage.
Ein besonders problemloses Zusammenstecken der einzelnen Kupplungselemente ergibt sich nach einer Weiterbildung der Erfindung dadurch, dass die Kupplungsstecker und/oder die Kupplungsmuffen federnd an dem Mastschlitten oder der Werkzeugeinheit gelagert sind. Die federnde Lagerung kann dabei nur an einem Hydraulikkupplungsteil oder vorzugsweise an beiden Kupplungsteilen vorgesehen sein. Dabei können die Kupplungsstecker beziehungsweise die Kupplungsmuffen einzeln gelagert sein oder die Kupplungsstecker und Kupplungsmuffen können insgesamt in einem Kupplungsblock fest angeordnet sein, welcher selbst federnd gelagert ist. Die federnde Lagerung kann über metallische Federn oder über elastische Gummielemente erfolgen.A particularly easy mating of the individual coupling elements results according to a development of the invention in that the coupling plug and / or the coupling sleeves are resiliently mounted on the mast carriage or the tool unit. The resilient mounting can be provided only on a hydraulic coupling part or preferably on both coupling parts. In this case, the coupling plug or the coupling sleeves can be stored individually or the coupling plug and coupling sleeves can be fixed overall in a coupling block, which is itself mounted resiliently. The resilient mounting can be done via metallic springs or elastic rubber elements.
Grundsätzlich können das erste Hydraulikkupplungsteil und das zweite Hydraulikkupplungsteil an einer beliebigen Stelle der einander gegenüberliegenden Seiten von Mastschlitten beziehungsweise Werkzeugeinheit angeordnet sein. Eine bevorzugte Ausgestaltung der Erfindung besteht darin, dass das erste Hydraulikkupplungsteil und das zweite Hydraulikkupplungsteil beabstandet zu der Mastführung angeordnet sind, wobei an der Werkzeugeinheit oder dem Mastschlitten zwischen den Hydraulikkupplungsteilen und der Mastführung ein Aufnahmeraum gebildet ist, in welchem mindestens ein Riegelbolzen der Verriegelungseinrichtung angeordnet ist. Dies hat den Vorteil, dass eine mechanische Verriegelung von Mastschlitten und Werkzeugeinheit nahe an der Mastführung erfolgen kann. Dies sichert eine besonders stabile Verbindung. Gleichzeitig sind die beiden Kupplungsteile weiter von der Mastführung beabstandet, wodurch ein leichteres und zuverlässigeres Zusammenstecken gewährleistet ist.In principle, the first hydraulic coupling part and the second hydraulic coupling part can be arranged at any desired location on the mutually opposite sides of the mast carriage or tool unit. A preferred embodiment of the invention is that the first hydraulic coupling part and the second hydraulic coupling part are arranged spaced from the mast guide, wherein on the tool unit or the mast slide between the hydraulic coupling parts and the mast guide a receiving space is formed, in which at least one locking bolt of the locking device is arranged , This has the advantage that a mechanical locking of mast carriage and tool unit can be done close to the mast guide. This ensures a particularly stable connection. At the same time the two coupling parts are further spaced from the mast guide, whereby a lighter and more reliable mating is ensured.
Der Riegelbolzen kann in verschiedener Weise ausgebildet und gelagert sein. Neben zylindrischen Bolzen sind auch bogenförmige, schwenkbare Riegelbolzen einsetzbar. Für eine besonders stabile Verbindung ist es nach einer Weiterbildung der Erfindung zweckmäßig, dass der mindestens eine Riegelbolzen quer zu einer Längsachse des Mastes gerichtet ist. Damit erfolgt die Verriegelung auch quer zur Bewegungsrichtung der beiden Schlittenelemente. Vorzugsweise sind zwei entgegengesetzt gegenüberliegende Riegelbolzen vorgesehen, so dass eine beidseitige formschlüssige Verriegelung am Mastschlitten erfolgen kann.The locking bolt can be designed and stored in various ways. In addition to cylindrical bolts and arcuate, pivoting locking bolts are used. For a particularly stable connection, it is expedient according to a development of the invention that the at least one locking bolt transversely to a longitudinal axis of the Mastes is addressed. Thus, the locking is also transverse to the direction of movement of the two carriage elements. Preferably, two oppositely opposite locking bolts are provided, so that a bilateral positive locking can be done on the mast carriage.
Weiterhin ist es nach einer Ausgestaltung der Erfindung bevorzugt, dass der mindestens eine Riegelbolzen durch einen zugeordneten Hydraulikzylinder angetrieben ist. Dabei kann je Riegelbolzen ein Hydraulikzylinder vorgesehen sein. Vorzugsweise wird der Riegel unmittelbar in Betätigungsrichtung des Hydraulikzylinders verschoben. Gemäß einer Abwandlung kann vorgesehen sein, dass ein Hydraulikzylinder zwei oder mehrere Riegelbolzen verstellt. Zwischen Hydraulikzylinder und dem einzelnen oder den mehreren Riegelbolzen kann ein Übertragungsmechanismus, etwa ein Keilschiebermechanismus, vorgesehen sein.Furthermore, according to one embodiment of the invention, it is preferred that the at least one locking bolt is driven by an associated hydraulic cylinder. It can be provided per latch bolt a hydraulic cylinder. Preferably, the bolt is moved directly in the direction of actuation of the hydraulic cylinder. According to a modification it can be provided that a hydraulic cylinder adjusts two or more locking bolts. Between hydraulic cylinder and the single or the plurality of locking bolts, a transmission mechanism, such as a wedge slide mechanism may be provided.
Die erfindungsgemäße Mastanordnung erlaubt mehrere Anordnungsvarianten der Verriegelungseinrichtung am Mastschlitten oder an der Werkzeugeinheit. Bei einem vorauseilenden Kuppeln der Hydraulikkupplung kann die Verriegelungseinrichtung insgesamt an der Werkzeugeinheit vorgesehen sein. Nach der hydraulischen Verbindung könnte so ein Hydraulikzylinder an der Werkzeugeinheit zur Verriegelung betätigt werden.The mast arrangement according to the invention allows a plurality of arrangement variants of the locking device on the mast carriage or on the tool unit. In an anticipatory coupling of the hydraulic clutch, the locking device may be provided on the tool unit as a whole. After the hydraulic connection such a hydraulic cylinder could be operated on the tool unit for locking.
Eine besonders zweckmäßige Ausgestaltung ist nach einer Weiterbildung der Erfindung dadurch vorgesehen, dass der mindestens eine Riegelbolzen an dem Mastschlitten angeordnet ist und dass im verbundenen Zustand von Mastschlitten und Werkzeugeinheit der mindestens eine Riegelbolzen in dem Aufnahmeraum an der Werkzeugeinheit angeordnet ist. Der Riegelbolzen ist bei dieser Anordnung an einem Mastschlitten jederzeit betätigbar, da er stets mit der Hydraulikquelle am Mastschlitten verbunden ist.A particularly expedient embodiment is provided according to a development of the invention in that the at least one locking bolt is arranged on the mast carriage and that in the connected state of mast carriage and tool unit, the at least one locking bolt is arranged in the receiving space on the tool unit. The locking bolt is actuated at any time in this arrangement on a mast carriage, since it is always connected to the hydraulic source on the mast carriage.
Weiterhin wird nach einer anderen Ausgestaltung der Erfindung eine besonders stabile Verriegelung dadurch erreicht, dass der Riegelbolzen in eine Riegelöffnung an dem Rahmen der Werkzeugeinheit einfahrbar ist. Es erfolgt also eine mechanische Verbindung unmittelbar am Rahmen, wodurch die Hydraulikkupplungsteile von mechanischen Beanspruchungen entlastet werden.Furthermore, according to another embodiment of the invention, a particularly stable locking is achieved in that the locking bolt is retractable into a latch opening on the frame of the tool unit. So there is a mechanical connection directly to the frame, whereby the hydraulic coupling parts are relieved of mechanical stresses.
Eine weitere Verbesserung beim Herstellen der hydraulischen Verbindung wird vorzugsweise nach der Erfindung dadurch erreicht, dass an der Werkzeugeinheit und/oder dem Mastschlitten mindestens ein Zentrierbolzen vorgesehen ist, welcher beim Zusammenfahren von Werkzeugeinheit und Mastschlitten noch vor einem hydraulischen Zusammenschluss mit einer Zentrierbohrung in den gegenĂĽberliegenden Mastschlitten beziehungsweise der gegenĂĽberliegenden Werkzeugeinheit in Eingriff kommt. Der Zentrierbolzen ist dabei am Rahmen von Mastschlitten oder Werkzeugeinheit oder vorzugsweise unmittelbar an einem der blockartigen Hydraulikkupplungsteile angeordnet. Vorzugsweise sind zwei oder mehr Zentrierbolzen vorgesehen. Der Zentrierbolzen weist an seinem freien Ende eine VerjĂĽngung auf, um das Zusammenschieben zu erleichtern.A further improvement in the manufacture of the hydraulic connection is preferably achieved according to the invention in that at least one centering bolt is provided on the tool unit and / or the mast carriage which, when the tool unit and mast carriage move together, precede a hydraulic connection to a centering hole in the opposite mast carriage or the opposite tool unit comes into engagement. The centering pin is arranged on the frame of the mast carriage or tool unit or preferably directly on one of the block-like hydraulic coupling parts. Preferably, two or more centering pins are provided. The centering pin has a taper at its free end to facilitate the pushing together.
Eine weitere bevorzugte Ausführungsform der Erfindung besteht darin, dass mindestens ein Hydraulikkupplungsteil eine verstellbare Abdeckung aufweist, welche bei einem Zusammenfahren der Hydraulikkupplungsteile von einer Abdeckposition in eine Freigabeposition verstellbar ist. Vorzugsweise ist an beiden Hydraulikkupplungsteilen jeweils eine Abdeckung angeordnet. Die Abdeckung kann ein verstellbares Plattenelement sein, welches beispielsweise durch eine Feder in der Abdeckposition gehalten ist. In der Abdeckposition sind die Kupplungsstecker oder Kupplungsmuffen durch die Abdeckung vor äußeren Einflüssen, insbesondere vor Verschmutzung, geschützt. Bei einem Zusammenfahren von Mastschlitten und Werkzeugeinheit kann über eine Betätigungsnocke das Abdeckelement entgegen der Federspannung aus der Abdeckposition in eine Freigabeposition bewegt werden, in welcher die Kupplungsstecker beziehungsweise Kupplungsmuffen der Hydraulikkupplungsteile frei liegen. Bei einem weiteren Zusammenfahren können so Kupplungsstecker und Kupplungsmuffen miteinander verbunden werden. Bei einem Auseinanderfahren wird dann das Abdeckelement durch die Federspannung wieder zurück in die Abdeckposition bewegt.A further preferred embodiment of the invention consists in that at least one hydraulic coupling part has an adjustable cover, which is adjustable from a covering position into a release position when the hydraulic coupling parts move together. Preferably, a cover is arranged on both hydraulic coupling parts. The cover may be an adjustable plate member, which is held by a spring in the covering position, for example. In the covering position, the coupling plug or coupling sleeves are protected by the cover from external influences, in particular from contamination. When the mast carriage and the tool unit move together, the cover element can be moved out of the covering position into a release position against the spring tension via an actuating cam, in which the coupling plug or coupling sleeves of the hydraulic coupling parts are exposed. In a further collapse so coupling plug and coupling sleeves can be connected together. When moving apart, the cover is then moved by the spring tension back into the covering position.
